Let `A = {phi , {phi, {phi}} , {phi , {phi}, {phi, {phi}}}}`, then total number of relations on A that are not function is equal toA. 27B. 512C. 485D. 1024 |

Answer» Correct Answer - C Let `= {phi, {phi, {phi}}`, …………… Here `n (A)=3` total no.of relations on `A = 2^(9)= 512` & total no.of functions on `A = 3^(3)=27` so no.of relations which are not function `= 512-27=485` |
